Techniques for improving the resolution of images (either analog images, analytic images, or images having a higher resolution than that of a display device) to be rendered on patterned displays. In one aspect of the present invention, an overscaling or oversampling process may accept analytic character information, such as contours for example, and a scale factor or grid and overscale or oversample the analytic character information to produce an overscaled or oversampled image. The overscaled or oversampled image generated has a higher resolution than the display upon which the character is to be rendered. Displaced samples of the overscaled or oversampled image are then combined (or filtered). An analytic image, such as a line drawing for example, may be applied to the oversampling / overscaling process as was the case with the character analytic image. However, since the analytic image may have different units than that of the character analytic image, the scale factor applied may be different. Since an ultra resolution image is already "digitized", that is, not merely mathematically expressed contours or lines between points, it may be applied directly to a process for combining displaced samples of the ultra-resolution image to generate another ultra-resolution image (or an image with sub-pixel information). The functionality of the overscaling / oversampling process and the processes for combining displaced samples may be combined into a single step analytic to digital sub-pixel resolution conversion process.

Systems, methods, and computer program products provide near real-time feedback to a user of a camera-enabled device to guide the user to capture self-imagery when the user is in a desired position with respect the camera and / or the display of the device. The desired position optimizes aspects of self-imagery that is captured for applications in which the imagery is not primarily intended for the user's consumption. One class of such applications includes applications that rely on illuminating the user's face with light from the device's display screen. The feedback is abstracted to avoid biasing the user with aesthetic considerations. The abstracted imagery may include real-time cartoon-like line drawings of edges detected in imagery of the user's head or face.

An improved portable game machine having a removably attachable external cartridge that includes an integrally formed image capturing apparatus is provided. The portable game machine preferably includes a user interface which may be manipulated by a user to capture images via the image capturing device of the external cartridge. The thus captured images may then be used in game play, or may be manipulated by the user to extend the range of enjoyment of the game. For example, according to the present invention, the user has the ability to associate hot spots with captured images which, when uncovered, cause the portable game machine to exhibit an effect associated with the hot spot. Additionally, the user is provided with the ability to incorporate line drawings or predefined stamp images into a captured image. The captured images may also be arranged to form an animation or loop of images that are displayed according to a sequence defined by the user. Another feature provided by the improved portable game machine of the present invention is the ability to print out composite images made up of a plurality of captured images. The composite image is typically larger than a single image, and therefore, is not easily displayed on a display of the portable game machine, but may be printed as a composite on an associated printer.

An animation system can vectorize an image by generating, from an input drawing, a dataset corresponding to vector and digital representations of the input drawing such that a rendering engine could render an image having features in common with the input drawing from the representations, as a collection of strokes and / or objects rather than merely a collection of pixels having pixel color values. A vectorizer might receive an input image, generate a particle clustering data structure from a digitization of the input image, generate a stroke list, wherein strokes in the stroke list correspond to clusters of particles represented in the particle clustering data structure, generate a graph structure that represents connections between strokes on the stroke list, and determine additional characteristics of a stroke beyond the path of the stroke, additional characteristics being stored such that they correspond to strokes. The strokes might be generated using global topology information.

Embodiments herein include a method, service, apparatus, etc., that automatically generates a coloring book image that includes line drawings defining a small number of color coherent, clearly discriminated, closed regions while preserving the basic semantic properties of the original image. These regions hence can be filled in with colored inks, crayons, paints, etc. The method inputs a color image that can be a photograph, scanned image, etc. The method begins by transforming the color image into a chrominance-luminance space and then performs low pass filtering on the color image that preserves the chrominance edges of the features within the color image. Next, the method segments the color image into the features based on locations of the chrominance edges of the features. Then, the method can merge selected features into other features. After performing any merging, the method identifies the remaining chrominance edges of the features within the image and adds lines along the remaining chrominance edges to form outlines of the features. Then, the method automatically filters out all other data from the image to leave only the outlines and produce a revised image consisting of just the outlines. The revised image of just outlines is then output to the user.

An image processing apparatus can obtain a copy image having excellent reproducibility with a relatively simple structure of a processing unit that processes image data. The image processing apparatus generates image formation data by processing image data.

A character / line drawing detection unit determines whether a part of the binary image data corresponds to a character / line drawing portion that consists of characters or line drawings so as to detect the character / line drawing portion. An image processing unit applies an image processing to the part of the binary image data by using an image processing method according to a result of determination of the character / line drawing detection unit.
